My two cents says that they are going to rollback to the VAB and deal with the battery problem and the ECO problems together.
They already pulled payload to make room for the Drive Lock Assembly I’m not sure they want to pull more.

R&R timeline shows five to six days at the pad to replace the feedthrough connector. Keeps Jan 10 doable.

There is no requirement for the WLE IDS batteries to be replaced. See earlier in the thread for the article we ran a few weeks back on this having flight rationale.
Looking likely that feedthrough connector will be R&Red at the pad (main area of conversation right now). -

Did they? I thought this mission had positive margins (and Columbus added to that when it proved to weigh less than expected) and the DLA was added without impact. I say that admitting I don't remember if I saw (or failed to see) any document proving otherwise.
In any case, pulling payload is never good... but neither is postponing the launch further!

If they R&R at the pad, will the flight rationale still be in place for the 10th?

According to the latest NASA TV schedule the STS-123 pre-flight briefings have slipped from Jan. 18 to:
February 5, Tuesday
8 a.m. - STS-123 B-Roll Video and Animation - JSC (Public and Media Channels)
9 a.m. - STS-123 Program Overview Briefing - JSC (Public and Media Channels)
10:30 a.m. - STS-123 Mission Overview Briefing - JSC (Public and Media Channels)
12:30 p.m. - STS-123 EVA Overview Briefing - JSC (Public and Media Channels)
2 p.m. - STS-123 Crew News Conference - JSC (Public and Media Channels)
This suggests that the Feb. 14 STS-123 launch date is being slipped and perhaps the STS-122 launch date is being slipped. -

The DLA had a negative impact to the middeck manifest. Keep in mind, it's not just weight, but it's also a matter of volume (hardware + foam + bag). -

The NASA TV schedule does not pre-empt the ongoing MMT meeting! That is totally seperate entities, so please be very careful not to jump to conclusions based on such low key information. -

Hale happy things didn't work well today (for data gathering).

Hale confirms problem is with the feedthrough connector.

Wayne Hale "Giga bites of data collected today!"

Specific element of the connector is the "pass through" area (where the pins are).
Reccomendations for forward work still being discussed.
"We're going to take this in a very systematic way". -
#255 by Chris Bergin on 18 Dec, 2007 20:38

"We owe an apology to the sensor guys" - the sensors are now not seen to be a problem (believe he's talking about since RTF).
No launch date decision today. Still NET Jan 10. -

"Launch schedule will not drive them to launch. Are going to get down to the problem and fix it"
"Part of the problem may be an installation problem" -
#257 by on 18 Dec, 2007 20:43
-
"Most of the feedthrough connector can be accessed from the outside of the tank"

Looks like we'll be covering this story for a number of days yet as they create the forward plan!

Lots of speculation questions being asked
